Vertebral Heart Score (VHS)

Published December 1st, 2024 by Orr Rubin

Vertebral Heart Score This is used to assess the size of the heart in relation to the spine, allowing for a more objective assessment of heart size. This score is calculated by measuring the length and width of the heart and comparing these measurements against thoracic vertebrae starting at T4. The VHS is considered normal if in; Cats is 6.8 - 8.0

Generalized Cardiomegaly

Published February 19th, 2025 by Orr Rubin

Generalized Cardiomegaly This refers to an overall enlargement of the heart. This enlargement can involve all chambers of the heart and can be caused by a variety of underlying conditions. Common symptoms can include coughing, dyspnea, exercise intolerance, increased respiratory rate or syncope. The cardiac silhouette is considered normal in size

Caudodorsal Parenchymal Pattern

Published December 1st, 2024 by Orr Rubin

Parenchymal Patterns Caudodorsal Parenchymal Pattern This test is used to characterize a specific distribution of lung pathology observed on thoracic radiographs. It refers to an abnormal increase in lung opacity that is predominantly located in the caudal and dorsal regions of the lungs. Several underlying diseases can lead to a caudodorsal parench

Left Atrial Enlargement (Canine Only)

Published February 19th, 2025 by Orr Rubin

Cardiac Panel Left Atrial Enlargement (Canine Only) This refers to an enlargement of the left atrium. This enlargement is often a sign of underlying heart disease and may be caused by mitral valve disease, dilated cardiomyopathy or congenital heart defects. Symptoms may include coughing, dyspnea, exercise intolerance, tachypnea or syncope. The left

Cranioventral Parenchymal Pattern

Published December 1st, 2024 by Orr Rubin

Pulmonary Panel Cranioventral Parenchymal Pattern This test is used to characterize a specific distribution of lung patterns observed on thoracic radiographs. It refers to an increased opacity or density in the cranial and ventral regions of the lung parenchyma. This pattern is often associated with a variety of respiratory diseases in both dogs a

Bronchial Pulmonary Pattern

Published December 1st, 2024 by Orr Rubin

Bronchial Pulmonary Pattern A bronchial pulmonary pattern is usually indicative of inflammation or infection within the bronchi and surrounding lung tissue. This pattern is characterized by increased visibility and thickening of the bronchial walls, and may be accompanied by other changes in the lung parenchyma. Conditions such as bronchitis, asthma

NA CVP/CDP

Published December 1st, 2024 by Orr Rubin

Pulmonary Patterns Cranioventral and Caudodorsal Parenchymal Patterns will not be assessed in the following scenarios; Not enough cranioventral or caudodorsal lung visible to assess. Poor patient positioning and poor image quality. Mass or other pathology present affecting visibility of the cranioventral or caudodorsal region of the lungs.

Thoracic Mass(es)

Published December 1st, 2024 by Orr Rubin

Thoracic Mass(es) Thoracic masses are abnormal growths that develop within the chest cavity. These masses can arise from various areas within the thorax, including the lungs, heart, mediastinum, pleura space, or chest wall. They can be benign or malignant. Depending on size and location, common clinical signs may include coughing, difficulty breathi

Diffuse Parenchymal Pattern

Published December 1st, 2024 by Orr Rubin

Diffuse Parenchymal Pattern A diffuse parenchymal pattern is characterized by a widespread change in the lung tissue's appearance. This pattern is often a non-specific radiographic finding and can be caused by various conditions, including pneumonia/pneumonitis, hematogenous spread, pulmonary edema or interstitial lung disease.
